How to edit the prompt of my generated video?

To edit the prompt of a generated video, select the Versions option located at the bottom left corner of the page.

Following that, select Edit Prompt to access the prompt box and make modifications.

Once you have made the changes, you can generate the video again.

Note: Regenerating from the prompt box will count towards your generation minutes, as it makes a new video for. You can always edit the script of the video as well and make changes as shown here.
